Blog

I write about things that catch my interest, from fitness and nutrition to science, technology, psychology, and whatever else I end up looking into.

Some posts are based on my own experiences. Others start with a question I want to answer, which usually means reading quite a bit, comparing sources, and figuring out what actually makes sense.

I've been blogging for a long time, but it's still a hobby. There's no strict posting schedule and no single subject I stick to. If something interests me enough to write about it, it might end up here.

You might be sitting on the couch right now, reading this on your smartphone. Your heart is beating, you're breathing, your eyes are moving across the screen, and your brain is processing the information. Even if you're completely relaxed and barely moving, there's a lot going on inside your body. Countless processes are happening at the same time, and many of them constantly require energy. And one molecule plays a central role in all of this: adenosine triphosphate, or ATP for short... Read More

When you're standing at the supermarket checkout these days, you've got quite a few ways to pay. You can tap your bank card, pay with your smartphone or smartwatch, and use not only your saved bank card but also other payment services like PayPal or apps linked directly to your bank account. Some places even accept cryptocurrencies by now. Or you can rummage around in your wallet for the right change, the old-fashioned way. And even though we're already paying digitally in all sorts of ways, Europe has been working on yet another option for a while now: the digital euro. If you're thinking, "Huh, what's this now? I already pay digitally!", let's take a closer look at what it's all about and why it could turn out to be a pretty interesting development for Europe and for us... Read More

Many of us are actually doing pretty well. We have things that would have been unimaginable luxuries just a few generations ago, and yet we still manage to find something that could be better. More money, a better job, a nicer home. And sure, we also know that plenty of other people have it much worse. That can make our own dissatisfaction feel almost a little uncomfortable, because we start thinking that we shouldn't really be complaining in the first place. But that usually doesn't make it go away. So let's take a closer look at why we get used to better circumstances so quickly, and why something that felt special yesterday can already feel completely normal today... Read More

Our Milky Way alone probably contains hundreds of billions of stars and possibly trillions of planets. We now know that planets outside our solar system, known as exoplanets, are widespread. And yet, we still have no confirmed evidence of life beyond Earth. So if even our own galaxy contains so many possible places for life, one pretty obvious question comes to mind: Where is everybody? And that is where the Fermi Paradox begins... Read More

The Dead Internet Theory claims that a large part of what we see online no longer comes from real people, but from bots, automated accounts and AI. In its most extreme form, the "real" internet is even supposed to have largely disappeared years ago. So let's take a closer look at how much truth there actually is to this pretty wild theory and why it has suddenly become more interesting again in the age of generative AI... Read More

Looking for a new hobby? Congratulations, the internet is full of lists ready to throw random suggestions at you, from archery to Zumba and everything in between. And sure, some of them might sound pretty interesting at first. But is that really something you'll enjoy? Something that could actually turn into one of your passions instead of ending up forgotten in a corner a few weeks later? Maybe it makes more sense to approach the whole thing from a slightly different angle and first figure out what actually fits you... Read More

You receive a compliment. Someone tells you that you did a great job, that you know what you're talking about, that you're actually really good at this. And before they've even finished the sentence, your mind is already trying to downplay it, searching for reasons why you probably didn't deserve the praise in the first place. Somewhere in the back of your mind, you keep waiting for the moment they finally figure it out. Welcome to impostor syndrome... Read More

When did you last have to wipe insects off your windshield after a drive through the countryside? If you have to think about it for a while, you are not alone.

It's hard to believe, but the foundation of this website dates back to 2006. That's why I created this 20 Years Special, where I share the story of how it all started. So let's go back to the beginning. Or maybe even a little earlier... Read More

It has happened to everyone at some point. You form an opinion and from that moment on, you almost automatically focus only on information that supports it. Contradictory evidence is ignored or dismissed as irrelevant. This is exactly where what we call confirmation bias begins... Read More

Imagine you're walking home after shopping in the city. Right in a busy pedestrian area, surrounded by lots of people, you see someone being attacked. Yet nobody does anything. Some just watch, others keep walking. What would you do? If nobody else reacts, you might assume there's no real emergency. Or you might hesitate, worried that you're misreading the situation and could embarrass yourself. This is exactly the kind of behavior described by what psychologists call the Bystander Effect...

Many of you are probably familiar with the concept of the multiverse from movies, comics and games. In different parallel worlds there exist various versions of a character who make different choices and follow alternative paths. I find such movies very entertaining. But did you know that behind this idea there are also serious scientific considerations? Today we will take a closer look at the different theories of the multiverse... Read More
